Toyota’s luxury Lexus brand will show a LF-Gh hybrid Grand Tourer concept at the New York International Auto Show next week, offering what the company claims are strong cues for the future design of Lexus production vehicles. Conceived as a redefinition of the luxury grand tourer, the lack of performance or rear-wheel drive powertrain details puts the emphasis on gauging public opinion of the distinctive new “spindle” front grille and lighting arrangement which is expected to become the frontal treatment of the brand. The concept’s aggressive visage emphasises aerodynamic efficiency and functionality thanks to pronounced radiator and brake duct treatment and a lack of door mirrors, presumably indicating the use of rear video vision.
